Cisco Systems 3560 Manual De Usuario

This chapter describes how to configure the Switch Database Management (SDM) templates on the 
Catalyst 3560 switch.

For complete syntax and usage information for the commands used in this chapter, see the command 
reference for this release.

This chapter consists of these sections:

You can use SDM templates to configure system resources in the switch to optimize support for specific 
features, depending on how the switch is used in the network. You can select a template to provide 
maximum system usage for some functions or use the default template to balance resources. For 
example, you could use access template to obtain maximum ACL usage.

To allocate ternary content addressable memory (TCAM) resources for different usages, the switch SDM 
templates prioritize system resources to optimize support for certain features. You can select SDM 
templates for IP Version 4 (IPv4) to optimize these features:

Access—The access template maximizes system resources for access control lists (ACLs) to 
accommodate a large number of ACLs.

Default—The default template gives balance to all functions.

Routing—The routing template maximizes system resources for unicast routing, typically required 
for a router or aggregator in the center of a network.

VLANs—The VLAN template disables routing and supports the maximum number of unicast MAC 
addresses. It would typically be selected for a Layer 2 switch.

In addition, the dual IPv4 and IPv6 templates enable a dual stack environment. See the

desktop switch.
